To all whom it may concern:

Be it known that I, RAYMOND H. Patron,

a citizen of the United States of America,

1 residing at Pittsburgh,in the county of Alle- 5 gheny and State of Pennsylvania, have invented certain new'and use Improvements inElectric Traps, of w the following i is a-specification, reference-being had there-v into the accompanying drawing.

This invention relates to anelectric trap for-extermi'nating rats or other rodents by theuse of electricity and has for its object to provide a trap ofsuch class in' a manner as ereinafter set forth which can besafely is employed by the public which can be oper-- ated with a minimum amount of current; which can be conveniently connected when desired with the electric circuit of an oflice' building, and which is so set up that after the am mal has been ,electrocuted, it can be conveniently removed fromthe casing of the 'trap.

With-the foregoing and other-objects in view, the invention gonsists .of the novel construct-ion, combination andarrangement of partsas hereinafter morespecifioa-lly descrlbed and illustrated inthe 'accom anying drawings wherein is she the pre erred embodiment of the invention,

- 80 understood that changes, variations and modifications canbe resorte'dto which come w1th1n the scope of the claims hereunto appended. i 7

In describing. the invention in" detail, refv erence is had to the accompanyingdrawings wherein'like reference characters denote cor-- respondingparts' throughout the several views-andin'which:

Figural-"is a longitudinal sectional as I of the trap.- Fig. 2 'is:a' horizontal section.- F g. 3-is acrossction, and, Fig. 4 'isa diagrammatic illustrating the electric wir,mg. 1

The trap comprises .a rectangular side walls 1?, 1 1 The top is including endwa'lls 1, 1,

and bottom 1", and-a to formed with; an openin medium of a door "2 w v 2. and also connected to the to ,1 y a has and sta 1e 2". The opening w 'ch 15 close by the v oor 2' white access casing-to ena lo the convenient removal of ea through the "the rodent afterit has been electrocuted.

' 1 Arranged, 'thin'the '1 are agair p5 of space partitions3,,3! whic extend om "but a. 1m. be

'ch' is hin ed as at to be hadtothe theend wall 1 tonear half the length of r the casing 1. .The partitions 3, 3 .are of a width equal to the width of the casing 1 and provide a passage for the rat to enter the trap. The end wall 1* is formed with an opening 4 which communicates with the passage 4 formed by the artitions 3, 3*, these latter extending inwardly and upwardly at an inclination. The inner end of thepartition 3 is formed with a vertically-extending portion'3 which is secured to a transversel extending support 3 attached to the si e walls 1", 1 of the casing 1. The inner end of the partition 3 is mounted upon a transversely-extending support 3 carried by the 70 bottom 1, The outer-ends of the partitions 3, 3 am connected to the end /wall 1". Extending parallel'with the support 3 and arranged in proximity to the end wall 1 isa'transversely-extending support 3 which hasthe lower end of a curved partition 3" supported thereon. a The partition 3? extends to tote 1 of the casing. Pivota y-connecte'd a'slat 5? 'to' the sup port 3 and extending toward the support 3 isan inclined pivoted platform 5 normally maintained in position through the medium of the. weights '6 which are connected with the platform 5 by the hangers 6. When the rodentjwalkson to the platform 5, it is lowered" and through the medium of a construction hereinafter set forth the rodent is 'electrocuted and'removed from the platform. 7 Projecting laterally from-the end wall 1 is a supporting bracket 9 upon which is 'mountedan electric-motor 9: having the "shaft 10 thereof "extended and journaled inthe side walls 11", 1. The shaft 10 is v'prm ided with a pronged scoop 11 which is arranged within the casing and which is adapted toscoo; up the rodent after beingeleetroouted an to deposit the same upon the inclined chute 12. The rodent after Lbeing deposited upon the inclined'platform 12 will slide down into the chamber 13 formed by the partition 3 in connection with one end wall, the side walls and the top and bottom of .thecasing. The opening closed by thedoor 2 permits of access being had tothe chamber 13 so that the electro- 105 outed rodent can be removed. The shaft 10 o is provided with a series of arms 14, each having its outer end .provided with a roller 15, the arms being of a length to cause the rollers 15 to retain the platform 5 depressed 110 while the rollers traverse the surface of the platform, these arms moving with the shaft 10.

The platform 5 has depending therefrom a contact 17 which when the platform 5-is lowered by the weight of the rodent engages with the contact 17 upon the support 3". A circuit wire 17 leads to the contact 17 and the circuit wire 17 leads to the contact 17 The wires 17 and 17 are in circuit with the motor 9. Circuit wires 17 and 17 form leads for the motor 9 and its circuit through the switch 17 the latter being connected to a source of electrical energy by the wires 17 and 17. The platform 5 is provided with a pair of metallic plates 18, 18*, the former being electrically connected to a circuit wire 18 and the latter to a circuit wire 18. The wire 18 leads to a pivoted switch arm 8 provided with a contact 8 adapted to bebrought into engagement with the contact 8, to which is connected a wire 19, the wires 19 and 18 being connected to a switch 19 connected to a source of electrical energy through leads 19 and 19 The switch arm 8 which forms a make and break device) is shifted through themedium of a lever arm 7 which at its upper end is connected to the free end of the arm 8 and at its lower end is attached to the plat-form 5 and by such an arrangement, it is obvious that when the weight of the rodent lowers the platform 5, the switcharm 8 will be shifted to close what may be termed the electrocuting circuit and further. that what may be termed the motor circuit is also closed through the contacts 17 and 17 actuating the motor and operating the scoop. The switches 17 and 19 are mounted upon the base plate 19 and are secured to-the end wall 1 of the receptacle.

The platform 5 is formed with an eX- tension 7 .which projects from the side wall 1 and it is to this extension that the lever arm 7 is attached, said arm 7 being arranged exteriorly of the casing.

From the foregoing arrangement and construction of parts, it is obvious that if the rodent travels through the passage 4* and upon the platform 5, the weight of the rodent will lower the door thereby closing the electrocuting circuit and alsothe motor circuit. The rodent will be electrocuted due to the closing of the electrocuting circuit and as the motor circuit is closed, the motor will be operated, moving the scoop to pick up the rodent from ofl the platform 5 and depositing the rodent upon the chute 12 from where it will be discharged into the chamber 13. As the movement of the rodent from the platform would affect the motor circuit, the traveling arms 14 act to retain the platform depressed until the scoop has passed to a position where the rodent will be discharged onto the chute 12.

What I claim is:,

1. In an electric trap, a counter-poised pivoted platform carrying contact plates insulated from each other and the platform and forming terminals of an electrocuting circuit, circuit connections leading to said contact plates, said connections including a make and break device operated by the movements of the platform, a'motor circuit including a make and break device controlled by the movements of the platform, a

motor in said circuit, and clearing mechanism operated by said motor while the platform is depressed.

2. In an electric trap, a counter-poised pivoted platform carrying contact plates insulated from each other and the platform and forming terminals of an electrocuting circuit, circuit connections leading to said contact plates, said connections including a make and break device operated by the movements of the platform and independent of the electrocuting circuit, a motor in said circuit, and clearing mechanism operated by said motor while the platform is depressed.

3. In an electric trap, a counter-poised pivoted platform carrying contact plates insulated from each other and the platform and forming terminals of an electrocuting circuit, circuit connections leading to said contact plates, said connections including a make and break device operated by the movements of the platform, a motor circuit including a make and break device controlled by the movements of the platform,

a motor in said circuit, and clearing mechanism operatedby said motor while theplatform is depressed, said mechanism including a shaft and a member; carried thereby adapted to retain the motor circuit active to carry the rodent away from the platform.

In testimony whereof .I aflix my signature in the presence of two witnesses.
